A fat mood is just one of those moods where you want to pull up at McDonald’s and order like 50 chicken nuggets bc a fat mood it’s also something you say when something just sounds good or relatable. The best way to say ‘a fat mood’ is to shout it very loud and annoyingly
My body: “I feel fat”
Me: *doesn’t care*
My brain: “nevermindddd”
To be in a fat mood is to think about your weightin a bad way even though you are happy with your weight so you don’t mind.
